[Woops. Didn't see your post. :c Awesome coincidence, however. <:]
I disagree with some of the clips in the opening - but the rest is fabulous.
The entirety of Korra just needs to be re-set to music from the Prince of Egypt.
[That one's amazing, too. I especially loved the end. And I agree.]
[That scream was so PERFECTLY placed. That was either meticulously set or accidentally awesome. I'm hoping for accidentally awesome - if I understand the comments on the youtube video correctly - the video was made before we knew that Amon and Noatak are brothers. Another case of accidentally awesome!
